In my game against the bot Alexander, I played 28. Bc4 (a blunder). Instead, the game report has as best move 28. Rh1!
I played from 28. Rh1 onward against Devon and Natasha. They both got mated in 4 or 5 moves. My understanding is that 28. Rh1 is good because it creates a mating net with the two rooks along the g and h files. Perhaps you have other ideas.
The full game is:
The problem with 28 Bc4 is that your bishop on h6 is vulnerable and overworked.
Against a stronger opponent, you would not be mating in 4 or 5 moves. 28..Bd2 costs you the exchange and stops your attack.
According to the computer, your Bc4 takes the evaluation from +11 to 0.0.
Rh1 protects the h6 bishop, allowing you to retreat your rook on g7 if necessary.
